Old dump site

My grandson and I found many bottles. Most are pepsi and are 10oz with no deposit no return on them. Some have bumps all over the bottle and others only have the bumps at the top and bottom. Also there is are a couple of mountain dew the same as the pepsi and a dominion bottle works kirkland lake bottle. This is just a few among the many we have found. Would I be correct in assuming they are from the 1950's. The dominion bottle looks like it has a dog or wolf on it.

Green embossed mountain dew if 80s i believe. Might have a date on the bottom.

No date on bottom. It says in the bottom not to be refilled in both english and french.
